Title: Amplifying circuit
Inventor: HIKITA JIYUNICHI
IPC: H03G5/00
Filed: 1983-04-30
Abstract: PURPOSE:To execute switching of a reproducing equalizer at a low cost, also to reduce a limit in a position of installation, and to make a device small-sized by providing a controlling circuit which is interlocked with a mechanical changeover switch, switches a buffer amplifier by a constant-current, and selects an optional feedback loop. CONSTITUTION:A buffer amplifier 2A and 2B are switched by a constant-current for driving each amplifier by a controlling circuit 3 interlocked with a tape changeover switch SW, and brought to on and off control. Therefore, when only the buffer amplifier 2A is on, an output of an amplifier 1 is fed back to a negative terminal of the amplifier 1 through a feedback loop containing a feedback resistance R3, and a high band time constant of this loop becomes (R2+R3).C1. Accordingly, an equalizer characteristic of an amplifying circuit in this case becomes that which is suitable for a normal tape. On the other hand, when only the buffer amplifier 2B is on, an output of the amplifier 11 is fed back to the negative terminal of the amplifier, respectively, and the high band time constant becomes R2.C1. Accordingly, the equalizer characteristic becomes that which is suitable for a metal tape.
